The analyzer in the writter is a WhiteSpaceAnalyser.
The 3 fields are Thickness, Width and Length, numerical values (Float), but not NumericField.

Doing a range query with a WhiteSpaceAnalyser on thickness and length is working perfectly, but width won't work.
How can I debug the query ?
I've tried looking in Luke, but they all "look" the same and programatically, they are created the same too.
